Abstract
Background:
Rapid escalation in textile, paper, pesticides, pharmaceuticals and several other chemical based
manufacturing industries due to amplification in human requirements have proportionately contributed to the extreme
contamination of water ecosystem, resulted from the discharge of toxic pollutants from industries. Effluents from textile
industries are comprised of coloured dyes like Rhodamine B, Methyl Orange, Methylene Blue and phenolic compounds
which deserve special mention owing to their non-biodegradable, carcinogenic and severe detrimental nature. Urgent
needs to ameliorate this fast declining environmental situation are of immense necessity in current scenario.
Objectives:
Objectives: In this regard, graphitic carbon nitride (GCN) is a distinguished material for water purification-based
applications because of its exclusive characteristics making it highly prospective for degradation of toxic dyes from water
by catalysis and adsorption techniques. GCN has been a material of conspicuous interest in recent times owing to its two
dimensional sheets like structure with favourable surface area, and cost-effective synthesis approaches along with high
production yield. This article presents a detail study of different aspects of GCN as a material of potential for water
purification. Through extensive literature survey it has been shown that GCN is an effective material to be used in the
fields of application. Several effective procedures like catalysis or adsorption for removal of dyes from water have been
discussed with their basic science behind.
Conclusions:
This systematic effort shows that GCN can be considered to be one of the most efficient water purifier with
further advantages arising from its easy and cost effective large scale synthesis.

Abstract
A lot of studies on spinel ferrites (MFe2O4, M = divalent metal ion) and their binary nanocomposites as photocatalysts in the decontamination of wastewater have been performed, because MFe2O4 nanoparticles are relatively stable, biocompatible and low-cost efficient photocatalyst. The separation of MFe2O4 photocatalyst is easy owing to its excellent magnetic behavior. With this background, the recent developments on photocatalytic performances of MFe2O4 based binary nanocomposites were comprehensively reviewed. Especially, a focus on MFe2O4/metal oxides, MFe2O4/carbon based materials, MFe2O4/polymers, MFe2O4/metal nanoparticles and MFe2O4/other compounds for the photocatalytic degradation of dyes, emerging contaminants and inorganic pollutants has been thoroughly given. The advantages of MFe2O4 based nanocomposites as photocatalysts were also discussed. In addition, the possible pathway of active free radical generation by these photocatalysts under visible and ultraviolet irradiation has been explained. A comparison of photocatalytic activities of MFe2O4 based binary nanocomposites with recent reports has been carried out. This review concludes that MFe2O4 based binary nanocomposites have potential capacity in water purification technology. Nevertheless, their practical utilization in water treatment plants still needs to be further studied.

Abstract
Super-hydrophobic porous absorbents are convenient, low-cost, efficient and environment-friendly materials in the treatment of oil spills. In this work, a simple Pickering emulsion template method was employed to fabricate an interconnected porous poly(DVB-LMA) sponge. A new co-Pickering stabilization system of Span 80 and NiFe2O4 nanoparticles was used to prepare ultra-concentrated internal phase water-in-oil (W/O) emulsions. After further polymerization, the resulting sponges were generated, which exhibited excellent adsorption selectivity due to the super-hydrophobicity and super-lipophilicity. Furthermore, the characterization results indicated that the composites had superior thermal stability, low density, high porosity and a flexible three-dimensional porous structure. Besides, the addition of nickel ferrite nanoparticles provided the materials with extra magnetic operability. High oil adsorption capacity (up to 36.9-84.2 g g-1), high oil retention, fast adsorption rate and superior reusability allowed the materials to be applied in the treatment of oily water.
